I am a similar build as you...I am 5'2 and 105lbs prepregnancy and I have already gained 25 lbs...I have started keeping a food diary 4 days ago and counting calories- not like a diet pregnancy but making sure I am not eating well over what I should...it is helping hold me accountable!

Maybe I need to start keeping a food diary to see how much I am eating. I feel like I eat very little cause I fill up pretty fast and then it takes forever to digest But maybe it is more than I think. I think part of my problem is I normally exercise my way through the pregnancy but I have felt so yucky that I have hardly moved
